Which of the following is a characteristic of a lever action firearm?
Setler79 [48]
I believe the answer would be A that you move the lever away from you to load the rifle (I know since I had such a rifle). This action places a shell into the firing chamber so that it is ready to fire so makes it convenient to re-load unlike where a shell must be placed in the chamber by hand each time such as is the case with many 0.22 rifles.

A physics student of mass 51.0 kg is standing at the edge of the flat roof of a building, 12.0 m above the sidewalk. An unfriend
balandron [24]

Answer:

Explanation:

The wheel and falling student will have common acceleration .

For rotational motion of wheel

Tx r = I α , T is tension in the crank , α is angular acceleration of wheel  , I is moment of inertia , r is radius of the wheel.

= I a / r

T = I a / r²

For motion of student

Mg - T = Ma , M is mass of the wheel.

Mg - I a / r²  = Ma

Mg = Ma +I a / r²

Mg = (M +I  / r²)a

a = Mg / (M +I  / r²)

= 51 x 9.8 / ( 51 + 9.6 / .3² )

499.8 / (51+ 106.67 )

= 499.8 / 157.67

= 3.17 m / s².

If time t is taken to  fall by 12 m

12 = 1/2 a t²

24 / a = t²

24 / 3.17 =t²

t²= 7.57

t = 2.75 s

velocity to reach sidewalk

v = u + at

= 3.17  x 2.75

= 8.72 m / s
